PROBLEM TO BE SOLVED: To provide a heat exchanger with a heat storage function capable of effectively preventing leakage of a heat storage material from the inside of a heat storage material container.SOLUTION: A cylindrical portion 32 is formed between peripheral edge belt-like portions of both container constitution plates 25, 26 of a cold storage material container 15 of an evaporator with a cold storage function. A part of a cylindrical heat storage material injection member 31 having a heat storage material injection path inside thereof, is inserted into the cylindrical portion 32 and brazed to both container constitution plates 25, 26. A collapsed portion 34 collapsed from both outer sides in a radial direction, is formed on a part projecting outward from the cylindrical portion 32 of the heat storage material injection member 31 to seal the heat storage material injection path by the collapsed portion 34. An uneven fitting portion 36 composed of a projecting portion and a recessed portion fitted to each other, is formed on a mating surface of deformation portions 31a, 31b of a peripheral wall of the heat storage material injection member 31, on a longitudinal section obtained by cutting a central portion in the width direction forming a right angle with a longitudinal direction and a collapsing direction of the heat storage material injection member 31 of the collapsed portion 34, along a longitudinal direction of the heat storage material injection member 31.SELECTED DRAWING: Figure 7 |
